Radio frequency engineer's job content:
Circuit system analysis: RF engineers should systematically analyze the whole RF system circuit, guide system design indicators, assign unit module indicators, standardize EMC design principles, and put forward the function and performance requirements of accessories.
Circuit principle design, including block diagram and circuit design, is a basic skill that RF engineers must have. It is also an extension of system design. The purpose of circuit principle design is how to realize the goal of system design.
In device selection and evaluation, it is essential to select the appropriate device to meet the circuit requirements. This process is carried out at the same time as the circuit principle design.
Software simulation, whether it is ADS, MWO, Ansoft, CST or HFSS, you always need to know how to use one or two simulation software. Although simulation software cannot make your design 100% accurate, it will always make your design deviate from the basic direction. So you must learn to use one or more simulation software. Its basic function is to enable you to qualitatively analyze your design. There will always be mistakes, but it can enhance your confidence.
PCB？ Layout, a PCB that meets the requirements, takes into account performance, appearance, technology, EMC and other aspects in layout and wiring. So PCB layout is also a very important skill.
Debugging analysis, this debugging is different from production debugging. Production debugging is mandatory, and the debugging of R&D products focuses on finding and solving problems. Many problems may not be found in the design, so you will know how to avoid these problems after debugging and how to improve them in the future. Debugging is also the most effective way to practice theory, and theoretical knowledge can be qualitatively understood through debugging process.
Testing, in fact, testing is for debugging, and debugging is for design. RF engineers must be proficient in using various RF test instruments, whether it is spectrum analyzer, network analyzer, signal source, oscilloscope, power meter, noise figure tester and comprehensive tester.
How to learn RF technology in practical work
Down-to-earth, modest, low-key, do more. Don't be a computer nerd or overstaffed. It's a matter of attitude.
For engineers who have just entered the RF field, they should first be a laboratory technician, that is, modest and low-key. Whether it is a product designed by others or a product designed by yourself, each resistor, capacitor and inductor should know its function and the meaning of each line should be clear. It is necessary to know why it is used and why it is routed like this. Don't be too technical, don't talk about experience, be practical.
If you have the above attitude, you will get twice the result with half the effort. The mentality is good, and the next step is to pay attention to the method.
What are the ways to learn RF?
Do not ask for answers. First of all, if you don't ask for an answer, you should jump over where you don't understand at the moment, and don't drill a dead end. The advantage of doing this is that you will read more and more, and your exposure will be wider and wider, just like reading a book. You can't understand the first part of the question. If you must ask for an answer, you may only read the first section of a year and still don't understand that question. And if you don't understand the question in the first section and it's not appropriate to ask people, then put it down and watch the second section, so that you can watch two sections, but you only understand one question. Very often, in the later chapters, you will probably solve the content that you couldn't understand before.
Laboratory. Laboratory. This is not a slogan, but a real sigh. I have never heard that you can learn microwave and RF well without going into the laboratory. Why are you in the lab? I don't want you to do general compulsory experiments, but I want you to do some research and development experiments.
Work notes, maybe few people will take work notes now. Anyway, I used to like taking work notes. If you are soft, you can't do hard. Challenge him. There's nothing to say about this. In a word, everyone has different views on the same question. Listening to other people's opinions is also a way to make rapid progress.
Brief introduction of RF circuit engineering;
Radio frequency engineer is a professional who is engaged in the design and development of the hardware RF part of the terminal product, and tracks and confirms the realization process of the product.
The work content is responsible for the feasibility analysis and implementation of RF related design schemes. Formulate and establish the development process, and complete the drafting and review of relevant products (such as schematic diagram, PCB board and BOM table, test and analysis report, etc.). ). Evaluate new suppliers and components of RF equipment; Work closely with the structural production department to ensure that the relevant objectives of the whole product are achieved as scheduled. Support and maintain the production line after the mass production of the project, and solve the problems related to the RF part. Provide RF technical support to other departments.
